I got this soldering iron from one my 3D printer repair customers. I'm not a fan of the temperature controls. I think it would be better with and up and down button. I do like how small it is. The stand is also very nice quality https://www.amazon.com/gp/product/B00ANZRT4M/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B00ANZRT4M&linkId=9d0cb849a1516c667c4c5da709363650

I've had this saw since I was 15 years old. This was a low end saw when I bought it 30 years ago. It was all I could afford at the time. Its impossible to find a Circular saw made in America now. We need to bring are manufacturing back the USA. I purposely bought a saw in craigslist to find an American made saw.

I bought this smooth stepper card on Amazon for $25. I wish there was some real specs on what a smooth stepper card does. I'm guessing the two processors can emulate more input and outputs. I hoping it can offload some the load off the computer. The little info I can find so a smoother step train pulse.

I'm finished getting the brushless spindle mount and tested. I decieded to change over to mach3, Mach3 seems like a more professional solution. I'm building this to learn CNC.

I've noticed for a while now that GPU's connected to monitors draw more power. When you are trying to lower the core voltage you might notice they cards will crash faster. In my case with the monitor connected I could not go below 725 millivolts. With the monitor disconnected I could get down to 695 millivolts . The experiment was a success Power Meter In This Video https://www.amazon.com/gp/product/B07HCPZ2GC/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B07HCPZ2GC&linkId=0e0b9d46e1d78df39af56a6dcee323a0

I'm shocked, B mode is awesome. I was able to save 55 watts. before you lower your core voltage you need to lower your clock. I'm running my core clock at 1250mhz. Every card is different on voltage.

There is no easy way to update your AMD GPU drivers easily in HiveOS, The only way I found so far is just reimage the mining rig. It took about 20 minutes to complete. Pretty simple if you know what to do.

One day my Keurig 2.0 starting leaking water from the bottom. This is device was not meant to be serviced, You can tell by how difficult it is to take apart. My high pressure relief valve became brittle and disintegrated. I was able fix using an automotive T-fitting. I cannot find internal replacement parts for this thing anywhere.

One thing I learned about crypto mining in the last few years is every GPU is different and has it own personality. Even GPU's from the same manufacturer and model behave differently. The trick is to place them in the rig were they get the best cooling. GPU's the have better heatsinks and fans go into hotter areas. GPU with smaller heatsink and less fans go the cooler areas.
